Object Storage Service:Rename a file (Go SDK V1)

Usage notes

• In this topic, the public endpoint of the China (Hangzhou) region is used. If you want to access OSS from other Alibaba Cloud services in the same region as OSS, use an internal endpoint. For more information about OSS regions and endpoints, see Regions and endpoints.

• In this topic, access credentials are obtained from environment variables. For more information about how to configure access credentials, see Configure access credentials.

• In this topic, an OSSClient instance is created by using an OSS endpoint. If you want to create an OSSClient instance by using custom domain names or Security Token Service (STS), see Configure OSSClient instances.

Sample code

The following code provides an example of how to rename the object srcobject.txt to destobject.txt in the examplebucket bucket.

package main

import (
	"fmt"
	"log"

	"github.com/aliyun/aliyun-oss-go-sdk/oss"
)

func main() {
	// Obtain access credentials from environment variables. Before you run this sample code, make sure that the OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET environment variables are set.
	provider, err := oss.NewEnvironmentVariableCredentialsProvider()
	if err != nil {
		log.Fatalf("Failed to create credentials provider: %v", err)
	}

	// Create an OSSClient instance.
	// Set yourEndpoint to the Endpoint of the bucket. For example, for a bucket in the China (Hangzhou) region, set the Endpoint to https://oss-cn-hangzhou.aliyuncs.com. For other regions, use the actual Endpoint.
	// Set yourRegion to the region where the bucket is located. For example, for a bucket in the China (Hangzhou) region, set the region to cn-hangzhou. For other regions, use the actual region.
	clientOptions := []oss.ClientOption{oss.SetCredentialsProvider(&provider)}
	clientOptions = append(clientOptions, oss.Region("yourRegion"))
	// Set the signature version.
	clientOptions = append(clientOptions, oss.AuthVersion(oss.AuthV4))
	client, err := oss.New("yourEndpoint", "", "", clientOptions...)
	if err != nil {
		log.Fatalf("Failed to create OSS client: %v", err)
	}

	// Specify the bucket name.
	bucketName := "examplebucket"
	bucket, err := client.Bucket(bucketName)
	if err != nil {
		log.Fatalf("Failed to get bucket '%s': %v", bucketName, err)
	}

	// The full path of the source object. The full path cannot contain the bucket name.
	srcObject := "srcobject.txt"
	// The full path of the destination object. The full path cannot contain the bucket name.
	destObject := "destobject.txt"

	// Copy srcobject.txt to destobject.txt in the same bucket.
	_, err = bucket.CopyObject(srcObject, destObject)
	if err != nil {
		log.Fatalf("Failed to copy object '%s' to '%s': %v", srcObject, destObject, err)
	}

	// Delete srcobject.txt.
	err = bucket.DeleteObject(srcObject)
	if err != nil {
		log.Fatalf("Failed to delete source object '%s': %v", srcObject, err)
	}

	fmt.Printf("%s has been renamed to %s\n", srcObject, destObject)
}
